[jQuery] using blockUI to block a select/dropdown list


Hi
I am trying to use blockUI to block a select/dropdown list named
'srv_voice' when an AJAX request is being processed.
Code is simply
$('select[name=srv_voice]').block();
I have used
$().ajaxStart($.blockUI).ajaxStop($.unblockUI);
to block the whole page so that part of the plugin works. Likewise I
have also blocked other div elements on the page. Why can I not block
this select box?
Does this plugin only support certain elements?
Thanks
Tom
